Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an L-shaped plug used for an antenna plug of a vehicle-mounted television and a method for assembling the L-shaped plug.

[0002]

2. Description of the Related Art An L-shaped plug is connected to a terminal of a coaxial cable that is wired in a direction orthogonal to a jack of an electric device such as an in-vehicle TV into which a plug pin is inserted.
The plug pin and the coaxial cable are assembled at right angles.

FIG. 5 shows a conventional L-shaped plug 100, in which a plug pin 120 is projectingly attached to one end of an L-shaped outer case 110 made of resin, and is orthogonal to the longitudinal direction of the plug pin 120. The coaxial cable 130 is pulled out from the end side.

The plug pin 120 has a cylindrical insulator 122.
The center pin 121 penetrates the inside, and the outer ring 123 is attached to the outer peripheral surface of the insulator 122. The base end of the plug pin 120 serves as a pin end 121 a protruding from the insulator 122 inside the outer case 110.

Further, inside the outer case 110, the coaxial cable 130 is end-processed so that the central conductor 131 is exposed from the insulating insulator 132 and the braided wire 133 is exposed from the insulating outer cover 134. ing.

In such an L-shaped plug 100, the exposed center conductor 131 is bent into an L-shape and soldered to the pin end 121a at the end of the center pin 121, while the exposed braided wire 133 is connected to the outer ring 123. By soldering to the plug pin 120 and the coaxial cable 130, the plug pin 120 and the coaxial cable 130 are electrically connected to each other in an L-shaped arrangement. In FIG. 5, 140 and 141 are soldering portions of these.

After each soldering is completed, the whole is surrounded by the outer case 110, the plug pin 120 and the coaxial cable 130 are fixed, and they are connected so as to be orthogonal to each other.

[0008]

[Problems to be Solved by the Invention] Conventional L-shaped plug 10
In 0, since the center conductor 131 drawn out for soldering to the center pin 121 is not completely covered with the braided wire 133 or other shield member, a high frequency signal passing through the center conductor 131 passes through the outer case 110 to the outside. Leakage to the center conductor 131 and external noise enters the center conductor 131. For this reason, when the L-shaped plug 100 is used for antenna connection of a vehicle-mounted television or the like, noise easily enters the received video or audio.

Further, the pin end portion 121a of the center pin 121
And the center conductor 131 or the outer ring 123 and the braided wire 133 are connected by soldering in a state where the plug pin 120 and the coaxial cable 130 are arranged orthogonally. Therefore, both the center conductor 131 and the braided wire 133 are connected. They must be bent at right angles and connected so that they do not touch each other.
The workability of the connection is extremely poor.

Further, since the soldered state cannot be temporarily held, the plug pin 120 and the coaxial cable 130 are mechanically fixed by enclosing them in the outer case 110 so as not to short-circuit each wire in the orthogonal state. The process was also difficult.

The present invention has been made in consideration of such conventional problems, and it is possible to suppress the intrusion of external noise into the center conductor of the coaxial cable, and to electrically connect the plug pin and the coaxial cable.

The connecting portion 43 can be bent up to a right angle.

Next, the assembling process of the L-shaped plug 1 thus constructed will be described with reference to FIG.

As shown in FIG. 4A, first, the coaxial cable 3 is connected to the shield case 4. In the shield case 4 for connecting the coaxial cable 3, the plug-side tubular body 41, the cable-side tubular body 42, and the connecting portion 43 are arranged in a substantially linear shape as shown in the figure. On the other hand, the end portion of the coaxial cable 3 is peeled off as described above, and the center conductor 31 and the insulating insulator 3 are inserted from the tip thereof.

Next, the central conductor 31 of the coaxial cable 3
Is soldered to the pin end portion 21b of the plug pin 2 to electrically connect the two. The solder connection work can be easily performed by the work through the opening 46 because the center conductor 31 and the pin end 21b face the opening 46, respectively.

After the solder connecting step, the connecting portion 43 is bent at a right angle as shown in FIG. 4 (d). In the state where the connecting portion 43 is bent at a right angle, the end faces 41a, 42a of the plug-side tubular body 41 and the cable-side tubular body 42 face each other, the opening 46 is closed, and the center conductor 31 and the pin end 21b are closed. The entire circumference is completely covered by the shield case 4.

The shield case 4 shown in FIG. 4 (d), in which the plug pin 2 and the coaxial cable 3 are fixed at both ends, is inserted into one of the two divided outer cases 5 formed to cover the whole, and then the outer case. The other case 5 is covered, and the two divided outer cases 5 are locked or adhered to each other to be integrated to form the L-shaped plug 1 shown in FIG.

In the step of covering with the outer case 5, since the plug pin 2 and the coaxial cable 3 are positioned at both ends of the shield case 4 bent into an L shape, they can be handled as an integrated part. The outer case 5 can be covered with a simple operation.

In the L-shaped plug 1 assembled in this way, the entire circumference of the central conductor 31 and the pin end 21b is completely covered by the shield case 4, so that the central conductor 3

In the above embodiment, the shield case 4 is used.
Although the coaxial cable 3 is attached and then the plug pin 2 is attached, the plug pin 2 may be attached first and then the coaxial cable 3 may be attached.

Further, in the above embodiment, the connecting portion 43
Is bent at a right angle, the center conductor 31 of the coaxial cable 3 positioned in the shield case 4 is bent,
The coaxial cable 3 may be fixed to the shield case 4 after the connecting portion 43 is bent, because the shield case 4 may come into contact with the shield case 4. That is, without crimping the caulking portion 42B, the coaxial cable 3 is inserted into the shield case 4, the pin end 21b of the plug pin 2 attached to the shield case 4 and the center conductor 31 are soldered, and the connecting portion After bending 43 at a right angle, the coaxial cable 3 may be pulled to such an extent that the center conductor 31 is not loosened, and the crimp portion 42B may be crimped from the outside of the braided wire 33.

The connection between the outer ring 23 of the plug pin 2 and the plug-side tubular body 41 does not necessarily have to be a snap-in connection, and for example, both may be connected by soldering.

Further, in the above-described embodiment, as an example of engaging and connecting the both, the engaging concave portion 44 is formed in the plug-side tubular body 41 and the engaging protrusion 23a is formed in the outer ring 23. The outer ring 23 is provided with an engaging protrusion on the side tubular body 41.
The engagement recess may be formed on the side.

Further, the outer case 5 may be covered with a synthetic resin in the molding step so that the shield case 4 is insert-molded, for example.
